So Dirac treats two subs as two independent speakers and doesn't optimize the combined response in any way?? Not good. It's important to keep in mind that Dirac isn't designed to do that. That's precisely why we need Emotiva to get the bass management for dual subs nailed down. Ok so we have confirmation on how Dirac will hadle the two subs. Now the only question remains is what was Emotiva's thinking behind the bass management? Or is the original dual mono what we should be using with Dirac and dual subs? while we can't individually change level and distance, does Dirac have that capability in thus mode? (and thus mode has just one EQ for the pair) |

OK, now you're giving my AWD car a bad time; it gets me through the snow so I'm happy.  To get you through the snow your AWD car should have some way to lock differential. Mine does it by applying brakes to the wheel that have least or no contact with surface. This way the power in directed to other wheels that have contact with surface. If differential was 'free' then even one wheel on the slippery surface would mean are are unlucky to stay at this place without external help. Like in this video... |

I'm more baffled why Dirac did sign off on optimizing subs independently. They should know better. It's important to keep in mind that Dirac isn't designed to do that.

noticed the exact same thing at my house.

Wonder if others are having this problem, not many people responding.

Wonder if others are having this problem, not many people responding. im sure you will get more responces tonight.. .. what if you use a y splitter out of the xmc 1 too the subs from the left mono that works..? good luck.. what kind of subs u running?  twin captivators S1 2400 watts rms 18 inch woofer big sealed box 4cuft what a monster |

It would work for a Mono output only, with one distance setting, but that is not what I expected or was promised, up until ScudDawg replied I wasn't sure and am still not sure if this was a common problem for many or just isolated to a few.
Emotiva could be better at getting out in front of potential problems, and let their customers know they will have a fix soon, or tell us these problems are isolated and send us a new unit.

I'm more baffled why Dirac did sign off on optimizing subs independently. They should know better. He clearly stated why - it is out of scope of the Dirac Live technology. Sure they know better, look at the Dirac Unison... But it is not what XMC-1 is licensing (and probably will not be able to run due to limited DSP resources), they are licensing Dirac Live. And so, optimizing dual-sub setup is in scope of bass-management as Dirac Live scope cannot be extended. |

@deltadube, I am using two HSU ULS15, not in the same league as twin Captivators, but still very nice.

Proper room optimization is "out of scope of the Dirac Live technology"? I don't agree I'm more baffled why Dirac did sign off on optimizing subs independently. They should know better.

Just a suggestion, you would probably get more responses if you had "XMC-1" in the thread title.
Cheers'Gary

I don't post much on hear but have been enjoying my XMC-1 for a little bit and so far its great unit. The issue above presented itself to me and the fix was to setup your subwoofer's up using the stereo sub option and from there you can setup the levels, distance etc on both the right and left sub channels and then switch back too dual mono.

Proper room optimization is "out of scope of the Dirac Live technology"? I don't agree Automated Room EQ in form of individual/isolated channel by channel calibration is the scope of Dirac Live technology. It is what it is (as it is with Audyssey MultEQ/YPAO/MCACC, and many many others). Bass management, multiple subwoofer control, sound field technologies etc. is out of it's scope. It does it's work well - calibrates every single device it is presented with to the target very accurately. It is the thing for what they get their licensing fees. Not less, not more. Why are you insisting on it doing someone else's work - I don't understand. As it is clear, that it is out of scope of the Dirac technology present on the XMC-1, we are not asking Emotiva to add some more complicated technology... but just asking a flexible enough Manual control for the Bass Management, so we can optimally combine our subs at the right time (before automatics take place) so they are presented to the Dirac Live in already optimized way for their interacting in the room. It is a simple solution that does not require changing/extending the scopes, any developments from 'the part provider' (and Dirac is just a part that Emotiva buys, and this part behaves well to it's specifications) and no major developments from the Emotiva or some other side. As simple as that. |

Same here. Dual mono gives test tone for one sub (in my case front) only. I now have them set as stereo.

Under Markus' guidance, I ran a few tests on the test tones being put out by the XMC-1. The only oddity uncovered is that the subwoofer test tone is ~9dB lower than the main channel tone when all trims, filters and distances are set to 0. Markus also pointed out that at this price point, it would be nice to have a user selectable LPF, and full bandwidth pink noise for use with a 1/1 RTA.

The full pink noise is only useful for those with a 1/1 RTA. Besides Markus who here has one? It would be a .001 percent used feature. The other issues need to be fixed first. Users are starting to notice. emotivalounge.proboards.com/thread/38492/dual-mono-subwoofer-bugs?page=1&scrollTo=665519I can only assume at this point that no beta testers had dual subs to test this .2 processor. At least it this will help them put out a better product. |
